Well, I gave in and bought a topre keyboard. And I have to say, it is quite different than any cherry board or rubber dome that I've tried. Not sure if it's better or worse yet, but it certainly is different. I think the cherry switch that it most reminds me of is the clears because of the large bump that occurs high up. But, honestly, it does seem to combine aspects of more "mechanical" boards with a certain feeling that SOME domes have that, frankly, isn't bad for me.
I got the uniformly weighted 55g model but it feels heavier than MX blues, which I thought were supposed to be 50 or 55g. Are they measuring different things or is it just something about how the force curves are different. Anyway, I guess time will tell how I like it in the long run. But am I glad I tried it? Absolutely. Am I intrigued enough to want to try their 45g model as well. I think so. Am I $250 glad and intrigued? Time will tell.
